1.6.7 DDR Bearing IP and IPX at the Same Time

DDR can bear IP and IPX at the same time on one dial connection. That is, when a call connection has been established, IP message and IPX message can be sent at the same time on this connection.

The following is the implementation solution of DDR bearing IP and IPX at the same time and oriented to point-to-point connection. Its hardware configurations and dial string configurations are the same as the configurations in the example “Point-to-Point DDR”

II. Configuration procedure

Solution 1: use Legacy DDR configuration mode to realize the following at the serial port:

1)Configure router A:

Quidway(config)# dialer-list 1 protocol ip permit

Quidway(config)# dialer-list 1 protocol ipx permit

Quidway(config)# ipx routing 1.1.1

Quidway(config)# interface serial 0

Quidway(config-if-Serial0)# ip address 100.1.1.1 255.255.255.0

Quidway(config-if-Serial0)# ipx network 1

Quidway(config-if-Serial0)# physical-layer async

Quidway(config-if-Serial0)# modem

Quidway(config-if-Serial0)# dialer in-band

Quidway(config-if-Serial0)# dialer-group 1

Quidway(config-if-Serial0)# dialer map ip 100.1.1.2 8810052
